A scientist investigated the effect of exercise on the breathing rate of four people. box
This is the method used.
1. Measure the resting breathing rate.
2. Exercise for 10 minutes.
3. Measure the breathing rate as soon as exercise stops.
4. Record the time taken for the breathing rate to return to the resting rate.
Table 1 shows the results.
